Defining Triaxial Ellipsoids for Irrotational Binaries: axes1.sph and axes2.sph

When constructing an irrotational binary, the code takes a spherical single-star model and deforms it into a triaxial ellipsoid. To do so, the code reads from a file named axes1.sph an ASCII list of three integers, representing the deformation in the three principal directions (it reads from axes2.sph as well if you declare the binary contains stars of unequal-mass). This file will also be created by testinput for your convenience. See Sec. 4.4 for more info.
