    • Added an option 'treat all letters as variables' which when selected will ignore any default interpretation of letters used as constants or units. For example, '7nm' is treated in Mathcore as 'seven nanometers' by default. The new flag will treat that as straight variables, therefore '7mn' (7 * m * n) will now validate equivSymbolically with '7nm' (7 * n * m).
    • Fixed issue with equivSymbolic not behaving as expected with expressions consisting of two non-combinable (decimal) terms.
