Resetting plot equations sets number of "found" diamonds to zero.
Initial refactoring towards responsive layout.
Does not include graph itself.
Equations used to generate "diamond" points contain only integer values.
Note this isn't the same as points always lying at integer values, which limits the possible number of plots.
Increases allowable gradient of generated straight lines, and ensures part of line lies within graph boundary.
Graph sizes according to page layout.
On page load only - not dynamically responsive.
