[FLASH-USERS] bad syntax in reading species

[William Raphael Hix]

Hi Anthony-

This is something which FLASH might want to look into extending.  +, - and other symbols are widely used in reaction rate compilations.  For example, the leading database for astrophysical nuclear reactions, the REACLIB database maintained by the JINA collaboration, has long used al-6 to denote the ground state of Al26 and al*6 to denote the long-lived metastable state.  It's much easier to maintain the code if the notation in the dataset and the notation in FLASH are consistent.
