28691e8e75 const, ref and iterator optimization 
1. Another set of arguments optimized:
* args-by-val converted to args-by-ref
* in some cases, reverse has been done, if that is better: if the
object's copy is modified in the func, it's better to avoid extra copy
from arg to local var
2. some const functions marked as such (this is just a beginning)
3. iterators were replaced with const_iterators where applicable
4. catches that catch std::exception& changed to catch (...) - that is
safer; if exception handling is restructured, this will have to be
reconsidered anyway
5. removed some basic structures' constructors; changed them to hold
const char*s to avoid unnecessary string constructions;
6. in some places, moved variable declarations to their definitions, to
avoid calling default constructors and then assigning
7. removed some unnecessary shared_pointers in favor of local objects;
8. in FORTRAN-style functions, added const specifiers to input doubles;
9. fixed a place where values were inserted into a map while iterating
through it
10. fixed is_valid_*_derivative: they could accept incorrect values and
throw when upper index is less than lower

Introduce CoolPropDbl to replace long doubles. This may help to overcome
possible portability problems, and test for efficiency and precision.

c3508c3f55 Added parallel evaluation of residual helmholtz terms 
Should in the end only slow down by 1.2x, but calculate at least up to second order derivatives all at once, so net speedup of 5 if calculating all first and second order partials !!
