Initializing help system before first use

# Model.run

Purpose
Execute the model with optional input data.
Synopsis
`function model.run(input_data=None, exec_params=None) -> dict`
Arguments

input_data | Dictionary of input data to pass to the model via the moselpy: driver. Keys are identifier names, values are Python objects convertible to Mosel types.
exec_params | Execution parameters as a string ( "PARAM1=val1,PARAM2=val2") or list of strings ( ["PARAM1=val1", "PARAM2=val2"]). Sets values for model parameters (defined in the parameters block) and control parameters of modules/packages ( e.g., "mypkg.param=value"). The special parameter workdir defines the initial working directory.

Return value
Dictionary of output data collected via initializations to "moselpy:"
Example
Run with input and output data:

    model = mp.load_model("model.bim")
    output = model.run(
        input_data={"x": 10, "arr": {1: 100, 2: 200}},
        exec_params={"VERBOSE": 1, "workdir": "/tmp"}
    )
    print(output["result"])

Further information
1. Input data is made available to the Mosel model via the moselpy: I/O driver in initializations from "moselpy:" blocks. No special compile options are required: the driver works with normally compiled models (no debug flags needed).
2. Output data is collected from initializations to "moselpy:" blocks and returned as a dictionary.
3. After execution, check Model.exec_status for execution status and Model.exit_code for the result value (from Mosel's exit statement, or 0 if not called). The exit_code is only meaningful when exec_status is ExecStatus.OK.
4. A model can be run multiple times. Model.reset is automatically called before each run to release resources from the previous execution.
5. Threading: The module holds Python's Global Interpreter Lock (GIL) during execution. Multiple Model instances can exist, but only one can execute at a time within the same process. For parallel model execution, use Mosel's mmjobs module within a single model or run separate Python processes.
