99ed4875e1 spreadsheet: support evaluation of shared formulas 
This seems to be very uncommon.

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.

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

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.

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.

b03eec358d spreadsheet: add xlsx2csv demo 
This demo program will extract either raw or formatted
values from a spreadsheet, creating one CSV file per
sheet.

d69cf90249 format: implement support for evaluating spreadsheet number formatting 
This adds support for extracting a cell's formatted value according to
the number format applied to the cell.  To do this we need to implement
a parser for Excel style format strings and support formatting numbers
according to that style.

This also enhances the General formatting to be much closer to what
Excel normally does. There are likely still a few corner cases where
Excel and gooxml differ, but hopefully not too many.

17a365ee93 spreadsheet: start adding support for formula evaluation 
We can take advantage of cached formula results that Excel/LibreOffice
insert to ensure that our formula results match the expected results.
