In this exercise, you are going to help high school sweethearts profess their love on social media by generating an ASCII heart with their initials:

     ******       ******
   **      **   **      **
 **         ** **         **
**            *            **
**                         **
**     J. K.  +  M. B.     **
 **                       **
   **                   **
     **               **
       **           **
         **       **
           **   **
             ***
              *

1. Get the name's first letter

Implement the HighSchoolSweetheart.first_letter/1 function. It should take a name and return its first letter. It should clean up any unnecessary whitespace from the name.

HighSchoolSweetheart.first_letter("Jane")
# => "J"

2. Format the first letter as an initial

Implement the HighSchoolSweetheart.initial/1 function. It should take a name and return its first letter, uppercase, followed by a dot. Make sure to reuse HighSchoolSweetheart.first_letter/1 that you defined in the previous step.

HighSchoolSweetheart.initial("Robert")
# => "R."

3. Split the full name into the first name and the last name

Implement the HighSchoolSweetheart.initials/1 function. It should take a full name, consisting of a first name and a last name separated by a space, and return the initials. Make sure to reuse HighSchoolSweetheart.initial/1 that you defined in the previous step.

HighSchoolSweetheart.initials("Lance Green")
# => "L. G."

4. Put the initials inside of the heart

Implement the HighSchoolSweetheart.pair/2 function. It should take two full names and return the initials. Make sure to reuse HighSchoolSweetheart.initials/1 that you defined in the previous step.

HighSchoolSweetheart.pair("Blake Miller", "Riley Lewis")
# => """
#      ******       ******
#    **      **   **      **
#  **         ** **         **
# **            *            **
# **                         **
# **     B. M.  +  R. L.     **
#  **                       **
#    **                   **
#      **               **
#        **           **
#          **       **
#            **   **
#              ***
#               *
