Class StaticTokenDefinition

A utility class to represent an ERC20 token metadata. Contains four fields:

Field	Type
address	Address
symbol	string
name	string
decimals	BigInt

It has a constructor to initialized an object:

constructor(address: Address, symbol: string, name: string, decimals: BigInt)

The class exposes two static functions:

1. getStaticDefinitions()
2. fromAddress()

getStaticDefinitions()

Returns an Array<StaticTokenDefinition> object with the token definitions defined with the function:
