## ABI-DECODER
Go library for decoding data params and events from etherem transactions. Inspired by [abi-decoder](https://github.com/ConsenSys/abi-decoder)
## Example
```go
var myContractAbi = `
[
{
"anonymous": false,
"inputs": [
{
"indexed": true,
"internalType": "string",
"name": "name",
"type": "string"
},
{
"indexed": false,
"internalType": "uint256",
"name": "age",
"type": "uint256"
},
{
"indexed": false,
"internalType": "address",
"name": "_addr",
"type": "address"
}
],
"name": "StudentAdded",
"type": "event"
},
{
"inputs": [],
"name": "addr",
"outputs": [
{
"internalType": "address",
"name": "",
"type": "address"
}
],
"stateMutability": "view",
"type": "function"
},
{
"inputs": [],
"name": "age",
"outputs": [
{
"internalType": "uint256",
"name": "",
"type": "uint256"
}
],
"stateMutability": "view",
"type": "function"
},
{
"inputs": [],
"name": "name",
"outputs": [

"internalType": "string",
"name": "",
"type": "string"
}
],
"stateMutability": "view",
"type": "function"
},
{
"inputs": [
{
"internalType": "string",
"name": "_name",
"type": "string"
},
{
