Reduce multiple precision settings to one (time increment)

Feature Request

Summary

The current mission_analysis standard method includes multiple possibilities of precision (from config):

        <precision description="Specify the calculation accuracy">           
            <acceleration_increment description="Step size regarding acceleration or deceleration">
				<value>0.5</value>
				<unit>m/s</unit>
				<lower_boundary>0.0</lower_boundary>
				<upper_boundary>340</upper_boundary>
			</acceleration_increment>
            <mach_acceleration_increment description="Step size regarding acceleration or deceleration as a Mach number">
				<value>0.005</value>
				<unit>1</unit>
				<lower_boundary>0.0</lower_boundary>
				<upper_boundary>1.0</upper_boundary>
			</mach_acceleration_increment>
            <altitude_increment description="Step distance for climb or descent">
				<value>5.</value>
				<unit>m</unit>
				<lower_boundary>0.0</lower_boundary>
				<upper_boundary>1000</upper_boundary>	
			</altitude_increment>
            <way_increment description="Step distance in x-direction">
				<value>1000.</value>
				<unit>m</unit>
				<lower_boundary>0.0</lower_boundary>
				<upper_boundary>1000000</upper_boundary>			
			</way_increment>
            <specific_air_range_check_increment description="Relative step distance in x-direction for automatic Flight level change check">
				<value>0.01</value>
				<unit>1</unit>
				<lower_boundary>0.0</lower_boundary>
				<upper_boundary>1.0</upper_boundary>
			</specific_air_range_check_increment>
        </precision>

To reduce the complexity, this could to reduced to a time_increment (e.g. 10s)

Why?

It adds the value of reducing the complexity of the possible user settings and amount of code in this tool

Acceptance Criteria

• Eliminate the multiple options in the code
• Introduce one increment
• Test for at least 3 settings (e.g. 5s, 10s, 100s)
• Update documentation
