+Package txprocessor is the module that takes the transactions from the input and
+processes them, updating the Balances and Nonces of the Accounts in the StateDB.
+
+It's a package used by 3 other different packages, and its behaviour will differ
+depending on the Type of the StateDB of the TxProcessor:
+
+- TypeSynchronizer:
+	- The StateDB contains the full State MerkleTree, where the leafs are
+	the accounts
+	- Updates the StateDB and as output returns: ExitInfos, CreatedAccounts,
+	CoordinatorIdxsMap, CollectedFees, UpdatedAccounts
+	- Internally computes the ExitTree
+- TypeTxSelector:
+	- The StateDB contains only the Accounts, which are the equivalent to
+	only the leafs of the State MerkleTree
+	- Updates the Accounts from the StateDB
+- TypeBatchBuilder:
+	- The StateDB contains the full State MerkleTree, where the leafs are
+	the accounts
+	- Updates the StateDB. As output returns: ZKInputs, CoordinatorIdxsMap
+	- Internally computes the ZKInputs

+The structure of the TxProcessor can be understand as:
+	- StateDB: where the Rollup state is stored. It contains the Accounts &
+	MerkleTree.
+	- Config: parameters of the configuration of the circuit
+	- ZKInputs: computed inputs for the circuit, depends on the Config parameters
+	- ExitTree: only in the TypeSynchronizer & TypeBatchBuilder, contains
+	the MerkleTree with the processed Exits of the Batch
+
+The main exposed method of the TxProcessor is `ProcessTxs`, which as general
+lines does:
+	- if type==(Synchronizer || BatchBuilder), creates an ephemeral ExitTree
+	- processes:
+		- L1UserTxs --> for each tx calls ProcessL1Tx()
+		- L1CoordinatorTxs --> for each tx calls ProcessL1Tx()
+		- L2Txs --> for each tx calls ProcessL2Tx()
+			- internally, it computes the Fees
+	- each transaction processment includes:
+		- updating the Account Balances (for sender & receiver, and in
+		case that there is fee, updates the fee receiver account)
+			- which includes updating the State MerkleTree (except
+			for the type==TxSelector, which only updates the
+			Accounts (leafs))
+		- in case of Synchronizer & BatchBuilder, updates the ExitTree
+		for the txs of type Exit (L1 & L2)
+		- in case of BatchBuilder, computes the ZKInputs while processing the txs
+	- if type==Synchronizer, once all the txs are processed, for each Exit
+	it generates the ExitInfo data
