/**
* Returns a normalized and checksumed address for %%address%%.
* This accepts non-checksum addresses, checksum addresses and
* [[getIcapAddress]] formats.
*
* The checksum in Ethereum uses the capitalization (upper-case
* vs lower-case) of the characters within an address to encode
* its checksum, which offers, on average, a checksum of 15-bits.
*
* If %%address%% contains both upper-case and lower-case, it is
* assumed to already be a checksum address and its checksum is
* validated, and if the address fails its expected checksum an
* error is thrown.
*
* If you wish the checksum of %%address%% to be ignore, it should
* be converted to lower-case (i.e. ``.toLowercase()``) before
* being passed in. This should be a very rare situation though,
* that you wish to bypass the safegaurds in place to protect
* against an address that has been incorrectly copied from another
* source.
*
* @example:
* // Adds the checksum (via upper-casing specific letters)
* getAddress("0x8ba1f109551bd432803012645ac136ddd64dba72")
* //_result:
*
* // Converts ICAP address and adds checksum
* getAddress("XE65GB6LDNXYOFTX0NSV3FUWKOWIXAMJK36");
* //_result:
*
* // Throws an error if an address contains mixed case,
* // but the checksum fails
* getAddress("0x8Ba1f109551bD432803012645Ac136ddd64DBA72")
* //_error:

/**
* The [ICAP Address format](link-icap) format is an early checksum
* format which attempts to be compatible with the banking
* industry [IBAN format](link-wiki-iban) for bank accounts.
*
* It is no longer common or a recommended format.
*
* @example:
* getIcapAddress("0x8ba1f109551bd432803012645ac136ddd64dba72");
* //_result:
*
* getIcapAddress("XE65GB6LDNXYOFTX0NSV3FUWKOWIXAMJK36");
* //_result:
*
* // Throws an error if the ICAP checksum is wrong
* getIcapAddress("XE65GB6LDNXYOFTX0NSV3FUWKOWIXAMJK37");
* //_error:
