Design proper API for data queries

[thk123]

Goals:

• flexible to different data requests
• allow computation to be done on the server end.
• flexibile towards converting between data in different units

Data format:

RowTitle?, ColumnTitle, 
RowTitle, UnitOfColumn, 
RowTitle, DATA
RowTitle, DATA

Request of the form:

/api/data

"SheetIdentifer[ColumnName] * AnotherSheet[Column][rowKey]" -> { column: "ColumnName", unit: "g other", [column data, ...] }

Where each element would be multipled by the value at AnotherSheet[Column][rowKey], with the units

Next step is to think of a few examples uses and get them working.

Find out individuals carbon budget by:

TargetCarbonEmissionsByYear / PredictedPopulationByYear
