From/to unified pair name/exchange specific name

Update: It's in The Manual now.

Furthemore, this should simplify unit tests for pair name conversion (since I think there are still issues with this)

Hey! Thanks again for feedback, it's very constructive. Sure, I will expose the mapping.
In fact one half of that mapping (symbol → product id → symbol) is already there (you can use it right away):

# Python (almost identical to same code in JS and PHP, except for syntax)
symbol = 'BTC/USD'
print (market.products[symbol]['id']) # print product id by symbol
print (market.productId (symbol)) # same as previous line
product = market.product (symbol) get a full product dictionary by symbol
print (product['id']) # same as previous output

Will upload the other half (reworked) soon.

Though, the existing mapping does not throw errors, but returns the input string untouched. I will update that part of the interface anyway.

This feature will soon be ready, btw, Product Ids And Symbols. The Manual is frequently updated, I'm adding more and more details into it, so it's worth revisiting from time to time. I will also update it and add the two methods proposed here very soon.

I've uploaded the interface to products, product symbols and product ids.
Here's how to use it:

import ccxt
k = ccxt.kraken ()
k.load_products ()

# symbol → product
k.products['BTC/USD']

# id → product
k.products_by_id['XXRPZUSD']

# symbol → id
k.products['BTC/USD']['id']

# id → symbol
k.products_by_id['XXRPZUSD']['symbol']

No functions, basic dictionaries indexed by appropriate fields. The are cached and can be force-reloaded if necessary.

You will get a userland standard Python exception if you access non-existent keys in these dicts.
I hope the above solution simplifies the usage, closing this issue down now. Will soon add it to the Manual. Thanks again!
