968e4ba29d spreadsheet: use ParseCellReference from reference package 
Drop the old cell reference parsing code and use the new code
that parses to a struct and identifies absolute references

988f2e3290 spreadsheet: move ColumnToIndex/IndexToColumn 
Create a spreadsheet/reference package and put these functions
there. This prevents both duplication across the formula &
spreadsheet packages and a cyclic reference.

89b1416b8f gooxml: rework how filenames are calculated 
This is needed for pivot tables, split out from that branch
so any further changes to filename handling will be easier in
master.

61b27ff447 spreadsheet: return cached formula values with GetString 
This seems to make sense, and probably doesn't hurt in any case.

Todd
780ee23e1a spreadsheet: use math.Big for SetTime/GetValueAsTime 
The conversion to float64 caused precision issues for
far future dates, this at least avoids the problem for
most likely all scenarios that matter and can be enhanced
by just adding more bits.

c5be4536a9 spreadsheet: support sorting a sheet 
The file format doesn't support sorting, so we
need to sort the sheet rows and renumber after sorting.

ad46a6ae15 schema: preserve extra content on CT_R/CT_SdtPr 
The extra content is non-standard, but Libre seems to support
it well so we just round-trip it for now.

09825ac816 schema: rework schema namespaces to work around Windows issues 
The go command on Windows doesn't like long path name. To
work around this, this is the first in a series of changes to
shorten the schema disk path structure in a few places.

Fixes #89

a6ae585a35 spreadsheet: record inf/nan as errors 
As you can't directly enter NaN/Inf in Excel, there's
no great way to verify behavior.  This just ensures
that setting NaN/Inf from Go will result in a #NUM!
error in Excel.

00be1d037c formula: support evaluating array formulas 
Array formulas are entered in Excel by pressing
Ctrl+Shift+Enter to finish the formula.  The resulting
formula is entirely in one cell, but its computed results
expand into cells the size of the array result.
