Add minimum distance test case that causes Newton's method to fail
Work around singular directions in Newton's method for small systems.
Removed unused variables.
Removed unused typedefs.
Code cleanup including generalizing the "small number" test on line 100.
Merge branch 'feature/Degenerate_Newtons_Method_Case' into develop
Add bounded minimum_distance surface search with initial guess.
Defined index_type needed for some algorithms using pseudo curves.
Fixed polynomial printing code. It was using the wrong typedefs.
Added ability to print 4-series airfoil pseudo curves.
Clarified input parameter ranges and improved the enforcement of the ranges in the setters.
Fixed bugs using uninitialized vector elements.
Updated creation of 4-digit airfoils as piecewise curves using exact thickness and camber line representations and series expansions for the cosine and sine terms.
Fixed bug in lower surface calculations and rederived the derivative terms.
Added debugging statements.
Added a member variable to allow user to set the degree of trig. expansion.
Updated the piecewise 4-digit creator tests.
