stubbed out and documented method for matrix chain multiplication
added file with enums for value precision and type
convert all primitive variables to NSNumber, arrays to NSData, introduce precision enum and parameters to appropriate inits, and differentiate between single- and double-precision accelerate functions
due to change in wording of identity matrix init
added some macros for value precision
remove static to dynamic converter
bring tests/demos up to new api with abstracted precision
proper retain strength
