-----------------------------------

Other opinions on the naming? Or other blockers for committing? I have not 
tested the latest change regarding decimal point support yet but will try to 
soon...

> Provides support for monetary values to Solr/Lucene with query-time currency 
> conversion. The following features are supported:
> - Point queries
> - Range quries
> - Sorting
> - Currency parsing by either currency code or symbol.
> - Symmetric & Asymmetric exchange rates. (Asymmetric exchange rates are 
> useful if there are fees associated with exchanging the currency.)
> At indexing time, money fields can be indexed in a native currency. For 
> example, if a product on an e-commerce site is listed in Euros, indexing the 
> price field as "1000,EUR" will index it appropriately. By altering the 
> currency.xml file, the sorting and querying against Solr can take into 
> account fluctuations in currency exchange rates without having to re-index 
> the documents.
> The new "money" field type is a polyfield which indexes two fields, one which 
> contains the amount of the value and another which contains the currency code 
> or symbol. The currency metadata (names, symbols, codes, and exchange rates) 
> are expected to be in an xml file which is pointed to by the field type 
> declaration in the schema.xml.
> The current patch is factored such that Money utility functions and 
> configuration metadata lie in Lucene (see MoneyUtil and CurrencyConfig), 
> while the MoneyType and MoneyValueSource lie in Solr. This was meant to 
> mirror the work being done on the spacial field types.
> This patch will be getting used to power the international search 
> capabilities of the search engine at Etsy.
