// FLEX - FLEX-GROW
/////////////////////////////////////////////////

ORIGINAL DEFAULT VALUE
flexGrow: '0',

EARLIEST NOTES
"0" so that it can more accurately be controlled by the column's flex parent settings

"1" so that columns actually respond more like a user would expect when adding a columns to a section & thus no min-width
is necessary

"0" so that column responds to a user's changing of the column's "align-self" property or the section's "align-items" property

removed in lieu of "grow" ("grow" now combines flex-grow w/ align-self & its options are intelligently presented & reset based
on parent flex settings & flex-basis settings)
