Adding CCi to M2

[MichaelABurr]

This is work started at the M2 conference in Madison. This is the pull request to add CCi support to M2. This includes implementations in the M2 language, the D-language, and aring support for polynomials and matrices in the back-end.

I'm taken away a bit by

i8 : # methods regularizedBeta                                                                       
                                                                                                     
o8 = 125  

for a method with basic usage:

regularizedBeta(x, a, b)                                                                
       * Inputs:                                                                                     
           * x, a "real number",                                                                     
           * a, a "real number",                                                                     
           * b, a "real number",                                                                     
       * Outputs:                                                                                    
           * a "real number",   

Indeed, $125 = 5^3$, but isn't it a bit too much?

Yeah, we could probably replace most of those with something like regularizedBeta(InexactNumber, InexactNumber, InexactNumber). I'll play around with it

[d-torrance]

This is a bit more manageable!

i1 : methods regularizedBeta

o1 = {0 => (regularizedBeta, Number, InexactNumber, InexactNumber)       }
     {1 => (regularizedBeta, InexactNumber, Number, InexactNumber)       }
     {2 => (regularizedBeta, InexactNumber, InexactNumber, Number)       }
     {3 => (regularizedBeta, Number, Number, InexactNumber)              }
     {4 => (regularizedBeta, Number, InexactNumber, Number)              }
     {5 => (regularizedBeta, InexactNumber, Number, Number)              }
     {6 => (regularizedBeta, Number, Number, Number)                     }
     {7 => (regularizedBeta, InexactNumber, InexactNumber, InexactNumber)}
