Problem: resizing the Boost resource graph calls
sched_data and infra_data ctors and dtors which
calls for planner to be changed from a struct
to a class.

Refactor the data structure into a class
with constructors, a destructor, and
assignment overload. Refactor direct
struct member access to public class setters
and getters, and public member functions.
Add private utility member functions and
data members. Maintain C client compatibility
by wrapping planner in a struct.

Add .hpp file to maintain C API compatibility while
enabling C++ features. Add a c_interface.cpp
to provide the external C functionality.

Problem: the current interface structure
facilitates C clients, but does not present
a separate C++ interface.

Separate the C and C++ interface to
enable different clients and facilitate
future planner extension.

Update the Fluxion build paths as well.

Add .hpp file to maintain C API compatibility

interface for separation of C and C++
clients and future extensibility.

Separate the C and C++ interface to

Problem: compilers variously generate warnings or
errors to indicate that rb_node_base_t is a
class not a struct.

Correct the typo.

Problem: restructuring planner as a requires
some utility member functions to be const.

Update the MT RBTree functions to provide
const overloads. Add clear function to
address memory leak from an uncleared
tree upon planner destruction.

Problem: restructuring planner as a requires
some utility member functions to be const.
While copying or assigning planners,
accessing elements of an empty tree
during the first iteration results
in undefined behavior.

Update the scheduled point RBTree functions
to provide const overloads. Add empty function
to allow checking for an empty tree
before iterating through the nodes
while copying or assigning planners.

Problem: Boost vecS container resizing
upon resource addition calls the
destructor and constructor for the
property maps (pool_infra_t and
schedule_t) associated with each
graph vertex.

Provide the constructor, destructor,
and assignment overload for schedule_t.

Problem: Boost vecS container resizing
upon resource addition calls the
destructor and constructor for the
property maps (pool_infra_t and
schedule_t) associated with each
graph vertex.

Provide the constructor, destructor,
and assignment overload for pool_infra_t.

Problem: the epoch value is uninitialized
in ephemeral_t, which causes comparisons
to be performed on the uninitialized member
variable.

Initialize m_epoch to 0.

Problem: comparing a uint64_t with int64_t
results in a compile time warning. Since
in this case the comparison just checks if
the uint64_t `remapped_id` is greater than
int64_t max value, static cast first.

Problem: without ctors, dtors, and
assignment overloads for planner and
planner_multi, Boost vecS resizing called
the schedule_t and pool_infra_t which
could not deep copy the structs. As
a result, the resizing caused all
allocations and reservations to be
destroyed. A check in resource-query
ensured resource graph mutation
could not be performed via `attach`
on a resource graph with allocations
or reservations.

Remove this restriction.

Problem: testsuite tests will need to compare
planners via the `==` operator to check if copying,
destruction, and assignment works as needed.

Add the required member checks and C interface
functions.

Problem: testsuite tests will need to compare
planner_multis via the `==` operator to check
if copying, destruction, and assignment works
as needed.

Add the required member checks and C interface

Add the required checks.

Problem: testsuite tests will need to compare
pool_infra_t via the `==` operator to check if copying,
destruction, and assignment works as needed.

Add the required member checks.

Problem: the testsuite needs to test
if copying, destroying, and assigning
planners works as desired. Namely,
calling the copy constructor should
deep copy planners, and assignment
should ensure the two planner's states
are independent but the same initially.
Mutation of a copy should not affect the
source object. Destruction should not affect
the source object.

Add low-level checks for planner behavior.

Problem: the testsuite needs to test

planner_multis works as desired. Namely,

deep copy planner_multis, and assignment
should ensure the two planner_multis' states

Mutation of a copy should not affect the
source object. Destruction should not affect

Add low-level checks for planner_multis behavior.

Add unit tests to ensure the copy constructor,
assignment overload, and equality overload
function as needed.

Add unit tests to ensure the copy constructor,
assignment overload, and equality overload
for pool_infra_t function as needed.

Add the schema tests to gitignore to ensure undesired
files in the directory are not tracked by git.

Add tests for attaching a new subgraph to an
instantiated resource graph and ensure the
allocations and reservations are not affected.
Test that the match policy selects appropriate
resources from the newly added subgraph.

Problem: schema_test01 and schema_test02 have
misspellings of "constructors" and "assignment."
Fix the spelling.

Problem: with GCC, Yggdrasil and Boost libraries generate
compilation errors related to missing template keywords
and maybe uninitialized values, respectively. Suppression
flags for GCC are unrecognized by Clang and produce
compilation errors.

Add conditional diagnostic pragmas to suppress the errors
for GCC but not Clang.

I missed some mergify requirements when transferring this, or maybe
updated them after.
