Sameer Agarwal 041f27516a Move CompactifyArray to array_utils. 
1. Rename it to MapValuesToContiguousRange.
2. Improve implementation to just use a vector.

Sameer Agarwal 5e8321c39a Validate ParameterBlocks before solve. 
Ensure that all parameter blocks have finite values
before the minimizer is called.

Sameer Agarwal 1fdc520f7b Refactor the array validation routines into their own file, as they are used by 
more than just the residual block evaluation routines now.
Check the step computed by the linear solver for finiteness, and terminate early
if it is not. This will prevent bugs where the solver continues to run after
encountering an nan.
