Missing direction information in reactions.dat file
The reactions.dat files list various known reactions. For each reaction, a list of "LEFT" and "RIGHT" compounds is provided. Many reactions also specify their REACTION-DIRECTION
which can be one of the following: 'LEFT-TO-RIGHT', 'RIGHT-TO-LEFT', 'PHYSIOL-RIGHT-TO-LEFT',
'PHYSIOL-LEFT-TO-RIGHT', 'REVERSIBLE',
'IRREVERSIBLE-LEFT-TO-RIGHT'
The problem is that many reactions don't have this field. Is it safe to assume that when REACTION-DIRECTION
isn't listed, the direction is left-to-right?
