Added functions and fixed bugs

As always, see Changes.txt

Fixed mlib.polygon.checkPoint

Also added some demonstrations and some more statistics functions.

Changed style

See Changes.txt for more.

README.md Fixes

That's it.

Bug Fixes

1.0.0.2

Added:

Removed:

• Ability to use a direction for Math.GetAngle's 5th argument instead of having a third point. See Fixed for more.

Changed:

• Changed README.md for clarity and consistency.
• Updated spec.lua
• See Fixed for more.

Fixed:

• Circle.IsSegmentSecant now properly accounts for chords actually being chords, and not secants.
• Circle.CircleIntersects now can return 'Colinear' or 'Equal' if the circles have same x and y but different radii (Colinear) or are exactly the same (Equal).
• Statistics.GetMode now returns a table with the modes, and the second argument as the number of times they appear.
• Math.GetRoot now returns the negative number as a second argument.
• Math.GetPercentOfChange now works for 0 to 0 (previously false).
• Math.GetAngle now takes only three points and no direction option.
• Typos in Shape.CheckCollisions and Shape.Remove.
• Fixed nil problems in Shape.CheckCollisions.
• Improved readablility and DRYness of Shape.CheckCollisions.
• Bugs in Shape.Remove and Shape.CheckCollisions regarding passing tables as arguments.

TODO:

• Add:
  • Frequency
  • Binomial Probability
  • Standard Deviation
  • Conditional Probability

Bug Fixes and Changes

1.0.0.1

Changed:

• Changes.txt now expanded to include short excertps from all previous

commits.

• Changed release number from 3.0.0 to 1.0.0.1
• Math.Round now can round to decimal places as the second argument.
• Commented unnecessary call of Segment.CheckPoint in Polygon.LineIntersects.
• Polygon.LineIntersects now returns where the lines intersect.
  • false if not intersection.
  • A table with all of the intersections { { px, py } }
• Same with Polygon.PolygonIntersects, Polygon.CircleIntersects,

Fixed:

• Error with GetSlope being called incorrectly.
• README.md Line.GetPerpendicularSlope misdirection.
• Same with Line.GetPerpendicularBisector, Line.Segment.GetIntersection,

Circle.IsLineSecant, Circle.IsSegmentSecant, Statistics.GetMean, Median,

Mode, and Range, and Shape:Remove, and fixed the naming for

Shape:CheckCollisions and Shape:Remove.

• Clarified README.md
• Made util SortWithReferences local.
• Errors caused by local functions.

TODO:

• Add:
  • Frequency
  • Binomial Probability
  • Standard Deviation
  • Conditional Probability

Cleaned up code, mostly.

Also updated spec.lua, but it's still untested, so it's not official.

Added GetSignedArea, changed syntax, removed things.

3.0.0

ADDED:

• Added function GetSignedArea.

REMOVED:

• Removed drawing functions.
• Removed MLib.Line.Functions entirely.

CHANGED:

• Changed all the names to CamelCase.
• Changed module name to MLib.
• Changed return order of GetPerpendicualrBisector from Slope, Midpoint to Midpoint, Slope.
• Changed returned string of MLib.circle.isLineSecant to be upper-case.
• Changed IsPrime to accept only one number at a time.
• Changed NewShape's type to Capitals.

---

Related to code:

• Added more accuarate comments.
• Made code more DRY.
• Made code monkey-patchable and saved space (by declaring all functions as local values then inserted them into a large table.

TODO:

• Make LineIntersectsPolygon return where intersection occurs.
• Ditto with PolygonIntersectsPolygon.
• Add:
  • Frequency
  • Binomial Probability
  • Standard Deviation
  • Conditional Probability

Bug fixes, mlib.shape:remove & demos added

More demos coming later, hopefully.
