568	psFits functions with 'ext' in name	robert.desonia@…	Paul Price	"Most of the functions with 'Ext' in the name implies that is works only with extensions, but that is not 
the case as most all of them work with the primary HDU too.  It probably would be better to replace 
'Ext' with 'Hdu'.  Also, many of these functions have two flavors, one for HDU by name and one for HDU 
by number.  If the assumption is made that by number is more basic/universal, the 'Num' suffix could 
also be dropped and a 'ByName' can be used for those functions that index by name.  For example: 

psFitsMoveExtName -> psFitsMoveHduByName
psFitsMoveExtNum -> psFitsMoveHdu
psFitsGetExtNum -> psFitsGetHduNumber
psFitsDeleteExtNum -> psFitsDeleteHdu
psFitsDeleteExtname -> psFitsDeleteHduByName
psFitsGetExtType -> psFitsGetHduType
psFitsGetExtName -> psFitsGetHduName
psFitsSetExtName -> psFitsSetHduName
