' DeleteBlankRows
' This function will delete all blank rows on the worksheet
' named by WorksheetName. This will delete rows that are
' completely blank (every cell = vbNullString) or that have
' cells that contain only an apostrophe (special Text control
' character).
' The code will look at each cell that contains a formula,
' then look at the precedents of that formula, and will not
' delete rows that are a precedent to a formula. This will
' prevent deleting precedents of a formula where those
' precedents are in lower numbered rows than the formula
' (e.g., formula in A10 references A1:A5). If a formula
' references cell that are below (higher row number) the
' last used row (e.g, formula in A10 reference A20:A30 and
' last used row is A15), the refences in the formula will
' be changed due to the deletion of rows above the formula.
