Programming validation

Program VALID adds the symmetric CV, while program VALIDLL gives the (asymmetric) low and the high values. 

The convergence criterion in BHCOAT is the same as that in BHMIE series are terminated after y + 4y1/3 + 2 terms. Unlike BHMIE, however, all functions, including logarithmic derivatives, are computed by upward recurrence it seemed pointless to compute these derivatives by downward recurrence when they are not the major obstacle to writing a program valid for an arbitrary coated sphere.

If interest is sufficiently high we may expand the component list to add higher carbon mtmber hydrocarbons or other light gases but this will require another set of program validation experiments betore t y could be ottered as another NBS-traceable standard.
